8 Claims. (Cl. 269-153) This invention relates to vises and particularlyto an improved vise jaw construction for gripping a plurality ofworkpieces.

In general, the vise of the present invention includes a base means thatsupports a pair of longitudinally spaced jaw means one of which movablysupports a pair of laterally spaced jaw means, whereby the vise isadapted to grip an assembly of workpieces on four sides.

In accordance with the present invention the apparatus further includesa novel actuating means for uniformly applying clamping force to boththe longitudinally and laterally spaced jaw means whereby the assemblyworkpieces are accurately positioned and firmly retained.

It is, therefore, an object of the present invention to provide a visethat includes a novel jaw construction for accurately positioning andfirmly retaining a plurality of workpieces.

It is another object of the present invention to provide an apparatus ofthe type described that is readily adjusted for accommodating varioussizes and quantities of workpieces.

It is still another object of the present invention to provide animproved vise jaw construction that can be readily installed onconventional machinists vises for the purpose of adapting the vise tofirmly grip and accurately position a plurality of workpieces to besimultaneously machined.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawings wherein a preferred form of embodiment of the invention isclearly shown.

In the drawings:

FIG. 1 is a side elevational view of a vise constructed in accordancewith the present invention; and

FIG. 2 is a plan view of the vise construction in FIG. 1.

Referring in detail to the drawings FIGS. 1 and 2 illus trate a viseconstructed in accordance with the present invention that includes abase means indicated generally at 20. The base means includes first andsecond longitudinally spaced jaw means 22 and 24.

A slide means indicated generally at 30 also includes bottom protrusions32 disposed in tracks 28 which movably mount the slide means on basemeans.

Slide means 30 is longitudinally driven by means of a screw indicatedgenerally at 34 that includes a threaded shank 36 disposed in a threadedbore 38 and an end provided with a spline 40 for attachment of anactuating tool. Two collars 42 and 44, which are pinned to screw 34 asseen at 46, retain the screw against longitudinal movement relative tobase means 20.

As is best seen in FIG. 2, slide 30 includes a transverse member 48secured to slide means 30 by screws 50 which extend through holes 66 inslide 30.

Transverse member 48 is also provided with laterally extending tracks 52and 54. A pair of lever mounting members 56 and 58 are slidably mountedin tracks 54 and provide means for mounting two levers indicatedgenerally at 60 and 62 for pivotal movement about pins 64.

The outer ends of laterally extending member 48 are strengthened againstbending stresses by screws 68 and 7t).

Jaw member 24 is provided with laterally extending slots 74 which formtracks for laterally spaced jaw members 76 and 78. V

Jaw members 76 and 78 include inclined cam surfaces 80 and 82 which arerespectively engaged by follower 3,182,990 Patented May 11, 1965portions 84 and 86 formed by the ends of levers'60 and 62. The otherends 88 and 90 engage jaw member 22.

In operation, laterally spaced jaw means 76 and 78 are moved inwardlyalong tracks 74 and into engagement with one side of the assembly ofwork pieces. Longitudinally movable jaw means 22 is next moved alongtracks 28 and into engagement with the assembly. Screw 34 is nextactuated to move slide 30 and bring levers 60 and 62 into the proximityof jaw members 22, 76, and 78. If necessary, lever mounts 56 and 58 areadjusted laterally to bring the levers into the force applyingconfiguration of FIG. 2. Screw 36 is next actuated to cause the leversto simultaneously apply force to the jaw member with the inclined camsurface and 82 serving to apply a torque about pin 64 which urges leverportions 88 and 92 against the opposite ends of jaw member 22 at thesame time jaw members 76 and 78 are urged. inwardly by followers 84 and86.

While the forms of embodiment of the present invention as hereindisclosed constitutes a preferred form, it is to be understood thatother forms might be adopted, all coming within the scope of the claimswhich follow.
